No matter where you work, DO NOT talk bad about any of your coworkers, EVER...because they WILL find out.

Don't participate in any of the gossip that goes on. If you hear it, just ignore it. Don't run and tell someone else or the person being talked about. Just go about your business.

This is honestly the best advice I can think of to give a new nurse just starting out on the floor somewhere. Just do your job.
